How to Apply Rust-Oleum Rock Guard Paint?

Ideal Conditions to Spray

Use outdoors or in a well ventilated area such as an open garage. Use when temperature is between 50-90°F (10- 32°C) and humidity is below 65% to ensure proper drying. Do not apply to surfaces that, when heated, exceed 200°F (93°C) or galvanized metal. Avoid spraying in very windy and dusty conditions. Cover surrounding area to protect from spray mist.

Surface Preparation

Wash the surface with a commercial detergent, or other suitable cleaning method. Rinse with fresh water and dry with a clean cloth. Remove loose paint and rust with a wire brush or sandpaper. Lightly sand glossy surfaces.


Shake can vigorously for one minute after the mixing ball begins to rattle. If mixing ball fails to rattle DO NOT STRIKE CAN. Contact Rust-Oleum. Shake often during use. Hold can 8-10" from surface and spray in a steady back-and-forth motion, slightly overlapping each stroke. Keep the can the same distance from the surface and in motion while spraying. Apply 4 or more light coats to build desired coating thickness, followed by one medium coat to achieve a smooth final film. Allow the coating to dry slightly (about 2-3 minutes) between coats. More coats will result in a thicker coating which is easier to remove when desired. Allow the coating to cure for 24 hours before washing. Do not use near open flame.
